  • WAVE is an academic (OCEEMlab) and industry (BlueGreen Geophysics) initiative to develop a standardized electromagnetic (EM) platform that streamlines EM data processing and visualization. WAVE will be lean, efficient, user-friendly, non-prone-to-user mistakes, and highly reproducible.

  • To enhance the operation of academic marine EM studies to industry standards, WAVE will provide EM scientists with a rigorous suite of data processing and visualization MATLAB-based GUI tools. The GUI includes benchmarking tools that are reliable, intuitive, systematic, and flexible to users’ needs. Hence, improving the overall quality of processed EM data, optimizing survey design, and generating models (Pseudosections and preliminary 2-D inversions) "on-the-fly" during the cruise.

  • WAVE will be freely available to the academic community in 2025 (via a GNU license) after being validated during the research cruise of the  ICEFLAME project.

SCA/DEM effective medium modeling


SCA/DEM rock physics modeling

  • SCA/DEM modeling: First principle physics to derive the effective properties of components in a mixture. Elastic and electrical physical properties calculations using a single microstructure —> an advantage other schemes do not offer. 

  • Self-Consistent Approximation (SCA): Effective medium model for composite containing multiple mineral phases that are independent of mixing order. Useful to calculate the physical effective properties of water-saturated sediments. Bulk/Shear moduli and Resistivity are computed for specific critical porosity (φc) – biconnected inclusions.

  • Differential Effective Medium (DEM): Used to model an effective medium by starting with a single material, to which inclusions are successively added Bulk (compression), Shear (stiffness) moduli, and Resistivity properties of inclusions are calculated for φ < φc (sediments) and φ > φc (brine). The effective properties are recalculated after each inclusion addition.

Potential applications

Cornutos 1.0 SCA/DEM modeling enables the computation of saturations of different phases of interest such as gas hydrates, freshened groundwater, and seafloor minerals enclosed in various phases (e.g., brine, sand, clay, quartz, basalt).
